- Product Highlights
- ELASTOLAR® Sealant is a fast-drying, vapor barrier sealant that can be top coated with most solvent-based, flexible, light-colored coatings without danger of bleed through. It is weather resistant and may be used outdoors without top coating.
- ELASTOLAR® Sealant is the preferred product for flashing projections and terminations where a complete moisture and vapor seal is required.

- Handling Conditions
- Store and apply between 40°F and 100°F.
- Always test plastic materials for compatibility when using a solvent-based product.
- When used in exposed locations without top-coating, this product may darken or discolor due to surface dirt pick-up.
- This will not affect its performance.
- Make certain this product is completely dry and the area is free from solvent odor if food is involved.
- Select Foster® 30-45N for joint sealing polystyrene foam insulations.
- Preparation and Application Information
Material Preparation
- Do not thin. Apply only to clean, dry, oil-free surfaces. Keep container closed when not in use.
Application
- Joint Sealant:
- Apply by trowel, putty knife, caulking gun or power extrusion. When sealing insulation joints, apply ELASTOLAR® sealant to the edges of abutting sections at 1/16 in. to 1/8 in. (1.6 mm to 3.2 mm) wet film thickness and press mating surfaces together firmly to squeeze out air bubbles and to obtain complete contact. Strike off excess sealant on surface with a trowel.
- Note: Pressurized piping made from copper and aluminum alloys may be susceptible to under insulation corrosion when moisture is present and in direct contact with many materials. When used as a joint sealant, direct contact between pressurized pipes made from these metals and the sealant should be prevented.
- Flashing Sealant:
- Sealant shall be applied over the adjoining surfaces a minimum of 2” (50 mm) and flashed a minimum of 2” (50 mm) in each direction onto adjacent insulation (or mastic) surface. Apply a tack coat at 1/16” (1.6 mm) wet film. Embed reinforcing membrane (Mast-A-Fab® or 10 x 10 glass mesh) into compound. Apply a finish coat at 1/16” (1.6 mm) wet film. Total film thickness to be 1/8” (3.2 mm) wet, giving a 70 mil (1.8 mm) dry film. Allow sealant to dry a minimum of 8 hours before applying finish mastic over its surface. When flashing, do not trowel out to feather edge, but maintain a minimum of 1/8” (3.2 mm) wet film thickness throughout entire area of use. For best application, the material temperature should be 60°F or higher.
- Metal Jacketing:
- Apply a 0.25” (6 mm) bead of sealant underneath the lap. Jacketing shall be firmly embedded and pulled up tight and banded in place. All overflow of sealant shall be removed with solvents.
Clean Up
- Use solvent such as chlorinated solvent (non-flammable) or mineral spirits (flammable) for cleaning tools and equipment.
